Jig (Casting & Pitching) Fishing on Lake Amistad
Lake Amistad · Texas · South Central
Amistad Reservoir sits on the Rio Grande just upstream of Del Rio, Texas, straddling the U.S.-Mexico border at an elevation of roughly 1,117 feet. The lake is a flooded canyon system — sheer limestone bluffs, submerged creek channels, and hard-rock points define the structure, and clarity frequently runs 10–20 feet in the main lake arms. Largemouth bass dominate the sport fishery, with smallmouth present in smaller numbers, and the forage base leans heavily on shad and crayfish tucked into the rocky substrate.
A lead or tungsten head with a weed guard, skirt, and soft plastic trailer. Fished on the bottom by pitching, casting, or slow-rolling. The jig imitates crawfish and bottom-dwelling forage. More big bass have been caught on jigs than any other lure category — it's the lure that separates serious anglers.

Seasonal Tactics on Lake Amistad
Lake: Pre-spawn largemouth push from 15–25 ft of water onto shallow limestone flats and secondary points through February and March; spawning activity peaks in the 58–65°F range, typically mid-March through April, and fish stack in protected coves off the main Rio Grande and Devils River arms. Swimbaits and big finesse jigs on 12–15 lb fluorocarbon are the go-to tools as fish transition up.
Jig (Casting & Pitching): Pre-spawn is prime season — pitch brown/green pumpkin jig to 45° bank transitions and rocky points.
Lake: By June, bass retreat to 20–35 ft of water along main-lake bluff walls and channel swings, suspending near shad schools above the thermocline. Vertical presentations — drop shots with 4-inch finesse worms, or deep-diving crankbaits worked along rock ledges — consistently put fish in the boat when surface temps push past 85°F.
Jig (Casting & Pitching): Football jig on offshore ledges 15–30 feet. Swimming jig around grass edges at dawn.
Lake: Falling water temps in October and November trigger shad migrations into the upper creek arms, pulling bass shallow again. Walking baits and medium-diving crankbaits like a Strike King 5XD worked over rocky flats in 8–14 ft produce some of the best topwater windows of the year.
Jig (Casting & Pitching): Swim a jig around baitfish schools near points and flats. Shad trailer colors in fall.
Lake: Winter on Amistad is mild compared to most of the country — water temps rarely drop below the mid-50s, and bass remain catchable through December and January on slower presentations. A 3/8 oz football jig dragged along hard-rock points in 18–28 ft, or a suspending jerkbait worked on long pauses in the upper arms, keeps fish coming to the net when other Texas reservoirs are locked down.
Jig (Casting & Pitching): Slowest presentation — drag a 3/8 oz football jig on deep hard bottom. Barely move it.
Best Conditions
All seasons, all depths, all cover types; most effective in 50–70°F water; excellent in pre-spawn and when fish are on hard bottom
Match trailer to conditions: craw trailer in cold water (slower fall, bigger profile), swimbait trailer when swimming, chunk trailer for flipping.
